I am executing following shell script which internally gives call to another shell script.

sample code
=====

#!/bin/sh
cd /nik/cli/

./kcli.sh
show service
exit

======

./kcli.sh shell script open another command line interface as shown below. i want to execute some command on it. I am not able to achieve it.

[root@localhost ~]# ./sample.sh
Newpromt>
Newpromt>


expected

[root@localhost ~]# ./sample.sh
Newpromt> show service
mt [Running] - Uptime 0 (days) 23:11:25
mgr [Running] - Uptime 0 (days) 23:11:18
mn [Running] - Uptime 0 (days) 23:05:35
command executed
[root@localhost ~]#


i tried with ./kcli.sh " show service ; exit " without any success.

any suggestions.

If you want the script to execute in same shell do . /Kcli.sh

try this:
( ./kcli.sh show service ; exit)

No its not working...some more solutions....

It might work this way:

If the script you're calling invokes the secondary shell, you have to figure out how it goes about doing that...because if it simply exec's it, there's not much you can do without changing some things.

You could possibly pass the command in as an arg and then modify kcli.sh like such:

######### example.sh ################
#!/bin/sh

./kcli.sh "some command"




######### kcli.sh ###################
# a few thoughts on how to get it working...
# by piping to the shell...
echo "$1" |/bin/bash # or whatever shell...

# or you can "abuse" su...
su --command="$1" some_user # as long as the user's shell is the target shell

# "here" document (already covered by previous post)

# various shells have various ways of executing commands in a non-interactive way...
# ksh, for example:
/bin/ksh -c "$1"



That should get you started...
